Multi-Joint Training versus Isolated Training for Core Development
June 1, 2017
Ground-based free weight lifts, especially the explosive Olympic-style lifts, are highly recommended for athletic conditioning for the core muscles. They can provide a moderately unstable stimulus to augment activation of the core and limb muscles, while still providing maximal or near maximal strength, velocity, and power output.

Growth Hormone Responses to Stress
June 1, 2017
Growth hormone release is affected by the type of resistance training protocol used, including the duration of rest periods. Short rest period types of workouts result in greater serum concentrations compared to long rest protocols of similar total work; however, at present it is not clear how the various molecular forms or types of growth hormones are affected by rest period duration.
